Abstract
The invention relates to a linear actuator () for an automobile transmission comprising an electric motor () for moving a transmission control member () between a plurality of shift positions, a spring () for driving the transmission control member () to an end position of the shift range in case of electric power failure, and a worm screw () to drive a displaceable worm wheel () with a pinion () meshing with a displaceable gear rack (). The transmission control member () is displaceably coupled to the worm wheel (). The gear rack () is blocked by an electrically activated lock against linear displacement with the spring () in a compressed state such that upon interruption of power supply to the lock the gear rack () is released and linearly displaced by the spring () thereby shifting the transmission control element () to its end position.
